EchelonGraph scoreMEDIUM confidence

This high-severity CVE scores 8.5 under a secondary CVSS source (NVD's own analysis pending). EPSS exploit probability: 0.2%, top 84% of all CVEs by exploit prediction. GitHub Security Advisory data not yet ingested — confidence will rise once GHSA publishes (typical lag: hours to days for open-source ecosystem CVEs; never for infrastructure-only CVEs).

Wekan is open source kanban built with Meteor. Prior to 9.37, Wekan DDP update allow rules in server/permissions/cards.js, server/permissions/lists.js, and server/permissions/swimlanes.js authorize against the stored source boardId and do not validate a new boardId in the update modifier. Any authenticated user with write access to their own board can call /cards/update, /lists/update, or /swimlanes/update to move cards, lists, or swimlanes into a private board they are not a member of. This issue is fixed in version 9.37.
